Why do people snort cocaine instead of drinking it or otherwise consuming it?

Got into a late night conversation and now I'm curious. What does science have to say?

Do all humans perceive colors on a equal spectrum (color blindness aside) or can certain individuals/groups perceive a wider or narrower scale?

Do scientists understand the internal anatomy of Dinosaurs or only the skeletal system?

Posted: 30 Jul 2017 10:35 PM PDT

Organs layout, vessels, neuro-anatomy. What are the tests or ways that they are trying to figure this information out. This applies to any extinct organism.

If you move a wild bug far from its home but the same environment will it go back home or make a new life there?

Posted: 30 Jul 2017 03:35 PM PDT

Like if you took a grasshopper from one side of a lake to the other, one mile away, could it make the trek home? Would it stay there and find a new cluster of grasshoppers like it? Would it starve and die?

If a helicopter hovers above the earth will the earth move under it or will the helicopter stay with the earth?

Why is the earths core so hot?

Posted: 30 Jul 2017 10:50 PM PDT

It's a question that has always bothered me. What exactly makes the Earth's core so hot? Why hasn't it cooled yet?

Regarding the matter-antimatter imbalance and neutrinos: Did the same (ever-so-slight) imbalance between matter and anti-matter apply to neutrinos as well?

Posted: 31 Jul 2017 06:00 AM PDT

I'm trying to ascertain whether some clue could be garnered if we study neutrinos and anti-neutrinos and the matter-antimatter imbalance in the early universe.

I'm thinking that because neutrinos so rarely interact they would have taken off at straight lines as space-time was being created.

The annihilation process that matter underwent with its antimatter counterparts wouldn't have (or would it?) applied to neutrinos.

Are there any studies that address this possibility, assuming it actually is a correct assumption on my part?

Is the charge time of a battery linear?

Posted: 30 Jul 2017 04:20 PM PDT

For example: If a battery charges from 0% to 33% in 10 min (not real life times, obviously) then will it be fully charged after 30 minutes? Or it depends on other factors like total capacity, or the current percentage?

The Earth's internal layers are predicted due to seismic waves and their difference in speeds travelling through them. How did we do the same for the other planets?

Posted: 31 Jul 2017 01:55 AM PDT

I've been through a few threads here that satiated my curiosity about the Earth. Now, I'm curious to know how we estimated the thickness and composition of the other planets. What method did we use to measure from the various satellites we've sent to our planetary neighbours? Thanks!

Why does the proton number define the properties of an atom?

Posted: 30 Jul 2017 03:35 PM PDT

Why is there so much diversity in atomic properties caused solely by changing their protons? Why does adding or removing a proton completely change their appearance and attributes?

Do earthquakes have a "season"?

Posted: 30 Jul 2017 05:03 AM PDT

I've been living in Northern Japan for over a year now and have noticed that last spring and summer there were MANY small quakes, like several a month, but in the winter and early spring they stopped, now they have started again so it has made me wonder if there is a "season" for earthquakes. (Or if it's just a coincidence since I have only been here for a short period of time.)

Can a diabetic die from eating too much cake?

Posted: 30 Jul 2017 10:51 PM PDT

So I know that a lack of sugar can kill diabetics quite quickly, but high blood sugar just seems to cause chronic issues, like infections.

Could they commit suicide by eating heaps of sugary food, and how long would it take?

Just watched a movie with a suicide like this but I'm doubtful.

Is it possible that new elements yet to be discovered will be considered stable, or will they all have extremely short half-lives?

Why does metal in a microwave spark?

Posted: 30 Jul 2017 02:56 PM PDT

I can't think of a physical principle that explaines this? It can't be the photoelectric effect right? Microwave photons are low energy. Anyone got an explanation for me?
